ABSTRACT:
In a conventional frictional force transmitting device used in a vacuum, a problem has arisen when the device performs a sliding action over a certain distance, that is, its frictional force suddenly drops, which makes it impossible for the device to fulfill a desired function of braking. The above-mentioned problem in the frictional force transmitting device used in a vacuum for performing the function of braking, transmitting a frictional force, and effecting acceleration or deceleration, can be solved by improving the device, that is, by means of making its two opposing frictional elements so as to be selectively pressed against each other, in which one of the frictional elements is made of metal or of non-metallic materials and the other made of organic frictional materials, wherein the one of the frictional element made of metal or nonmetallic materials has surface roughness coarser than 3 microns in maximum height(Rmax) and is coarser than the other made of organic frictional materials.
